United States Patent 1 2,853,072 DRAIN SACK HOLDER Peter J. Fischer, Milwaukee, Wis. Application December 31, 1954, Serial No. 479,195 2 Claims. (Cl. 128-283) The invention relates to what may be termed a colostomy drain sack holder.

After a colostomy operation in which an incision is made through the abdominal wall and a part of the intestine is brought out and the diseased part removed, the ends of the severed intestine are brought out through the abdominal incision and the upper cut end is allowed to drain in a sack either for a certain period before joining the cut ends together or in some instances the drainage from the upper end continues as long as the patient lives. The present invention is concerned with a new and improved holder for the sack that receives the drain from the intestine.

The known forms of sack holders have a substantially flat body contacting portion and an upper cavity that curves outwardly to a substantially straight front wall that extend-s down to well below the horizontal center line ofthe holder, and the strap attaching buttons or other means for connection with the supporting strap are disposed on a line passing through the horizontal center line of the holder. With these known forms of holders it frequently happens that a discharge from the intestine acts on the straight front wall of the holder with sutficient force to lift the upper portion of the holder free of the patients body, and leakage of the intestinal discharge occurs between the body and the upper part of the bag carrying holder which is highly objectionable as this may occur under circumstances where the patient cannot give this leakage condition proper attention. I

The object of the present invention is to provide a sack holder which because of structural changes will prevent leakages of the above type from occurring. To this end the base of the holder instead of being straight is curved to closely fit the general curvature of the abdominal wall, the strap attaching means have been raised above the center line to secure a better gripping pressure at the base of the holder over the cavity portion thereof, the opening through which the sack extends has been enlarged by bringing its upper side closer to the center line of the holder, and the wall of the upper cavity instead of merging into a straight wall is inclined outwardly to its lower end so that its width at the center is almost twice the width of the conventional holder with the result that when an intestinal discharge takes place, the discharge will not exert a straight outward pressure tending to separate the bag and its holder from the body, but the forces of the discharge will be resolved in a downward direction,

and with the better anchorage above mentioned leakage will be prevented.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. l is a perspective view of the improved holder I inan operative position;

Fig. 2 is a detailed sectional view of the improved holder taken on the line 2-2 of Fig. 3.

Fig. 3 is a front elevation view of the improved holder;

Fig. 4 is a top plan View of the improved holder.

The holder of a suitable plastic composition has a circular base portion 7 provided with an annular groove 8 in which the folded over open end of the flexible sack 9 is held by a cord or elastic band 10. The bottom 11 of the base portion 7 is curved from its sides to the vertical center line as shown in Fig. 4 so as to better fit ice the curved abdominal wall of the patient as compared with the flat bottom of the conventional holder.

The strap attaching buttons 12 that fit into holes in the supporting strap 13 are arranged in a line parallel to but above the center line AB through the holder as compared to similar buttons for the conventional holder which are arranged on the center line.

The lower edge 14 of the cavity wall 15 has been brought closer to the center line AB to provide a larger opening 16 through which the bag extends as compared to the edge of the conventional holder.

The cavity wall 15 curves outwardly as indicated at 17 in Fig. 2 and then inclines or further diverges outwardly as at 18 so that on a vertical center line the width of the opening 19 is ten percent greater than that of the opening of the conventional holder so that, when the upper end 24) of the draining intestine discharges, its force will not be exerted against a straight wall such as the wall of the conventional holder tending to separate the holder and bag from the body of the patient but will be resolved in a downward direction, and since the curvature of the base of the holder and the raising of the buttons 12 above the center line permit a better holding action of the strap, the holder and bag will be firmly held to the body of the patient and seepages or leakages occurring in the use of the conventional bag holder will be prevented.

As shown in the drawing, the width of the cavity at its center is at least nine-tenths of the radius of the base opening and the area of the opening substended by the chord formed by the mouth opening is at least forty-five percent of the area of the opening of the base portion.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. A one piece drain sack holder of the character described having a circular base portion, having a bottom curving inwardly from its sides to conform to the curved wall of the abdomen, a cavity portion, and spaced strap attaching means on the midportion of the cavity portion olfset upwardly from the horizontal center line through the holder to increase the gripping action of the strap on the cavity portion of the holder.

2. A drain sack holder of the character described having a circular base portion and an upper cavity portion flaring outwardly from said base portion to the midsection of said cavity portion and then diverging further outwardly to a lower mouth edge whose width at its center is at least eight-tenths of the radius of said base portion so that the pressure of a discharge into the sack will be resolved continuously and predominately downwardly to prevent such discharge pressure loosening the holder from body contact and whose mouth portion terminates below the center line of the holder on a chord providing a sack opening of at least forty-five percent of the area of the opening of said base portion to further relieve lateral pressures of the discharge through the sack on the holder, and means engageable with the cavity portion of the holder above its horizontal center line in the region of its outwardly diverging mouth portion to firmly hold the base portion of said holder against the abdominal wall of the patient.
